Title: Hand-operated riveting appliance
Inventor: WUENSCHE RAY DIPL ING
IPC: B21J15/06
Filed: 1993-03-02
Abstract: On a conventional hand-operated riveting appliance for processing mandrel-type blind rivets, blind studs and collars of shear-tension stud systems, a holder for a magazine and a mouthpiece sleeve for receiving and processing a connector inserted into a mouthpiece are fitted, the magazine containing a number of mouthpieces into which the connectors can be inserted, and the mouthpieces contained in the magazine and provided with connectors are inserted successively into the mouthpiece sleeve by in each case moving the magazine away from the mouthpiece sleeve in the setting direction of the connector, then sideways and back onto the mouthpiece sleeve. In the case of air-operated riveting appliances, the movement can be brought about pneumatically by means of the compressed air flowing out of the appliance. It is thereby possible to process a whole series of connectors one after the other without having to grip each individual connector in each case. In addition, the mouthpiece changes which are otherwise required in some cases are eliminated.

Title: Intermittent-motion mechanism
Inventor: VOGEL WERNER
IPC: F16H27/06
Filed: 1993-03-31
Abstract: A description is given of an intermittent-motion mechanism with a driven rotor shaft, a driver part arranged on the rotor shaft and having a driver, an indexing shaft, an indexing cross arranged on the indexing shaft and having indexing fingers with which the driver enters into contact and moves the latter onwards in steps and an indexing plate arranged on the indexing shaft for the purpose of fixing workpieces and the like. The driver, which is designed as a pin, enters into radial recesses in the indexing cross and leaves them again, the indexing cross thereby being rotated in steps. The actual indexing operation takes place over a rotation of the rotor shaft through 90 DEG , while over the remaining 270 DEG  the indexing cross and hence the indexing plate is locked, allowing machining of the workpieces etc. to be carried out in this time. The intermittent-motion mechanism is distinguished by a high indexing performance and a particularly compact construction. <IMAGE>

Title: Method and device for composting material which rots
Inventor: EMDE PETER DR ING
IPC: C05F17/02
Filed: 1993-08-20
Abstract: The invention relates to a method and a device for tunnel composting material which rots which consists of mainly biological waste in a rotting space with humidity and air regulation and mechanical relayering of the material which rots. The rotting space (2) consists of a number of horizontal shafts (6) which are arranged above one another and which are in each case closed by inner (7) and outer flaps (12). Arranged in the horizontal shafts (6) are constructionally identical belt conveyors (4.1-4.5) which in each case run in opposite conveying directions and relayer the material which rots (1) from level to level. Prepared material which rots (1) is applied to the conveying belt (5) of the top belt conveyor (4.1) through the closable filling opening (10). After a certain maturing and storage time, the superposed material which rots (1) is transferred, by the belt conveyor (4.1) which has been set in operation, onto the belt conveyor (4.2) where it then remains lying motionless for further rotting. During the rotting phases, the material which rots is moistened and aerated as required. This relayering rhythm is continued until all belt conveyors (4.1-4.5) are covered and, after repeated alternating of remaining still and movement of the belt conveyors and also with corresponding supply of process air, the maturing process is completed. <IMAGE>
